System and method for improving memory resource allocations in database blocks for executing tasks

ABSTRACT

A system for improving memory resource allocation efficiency for executing tasks receives a request to allocate a particular amount of memory resources to a particular database block of a database server. The system monitors the database blocks of the database server to determine whether any portion of memory resources already allocated to any of the database blocks is unutilized. If it is determined that a portion of the memory resources already allocated to any of the database blocks is unutilized, the system reallocates the unutilized memory resources to the particular database block.

TECHNICAL FIELD

The present disclosure relates generally to database management, and more specifically to a system and method for improving memory resource allocations in database blocks for executing tasks.

BACKGROUND

It is challenging to determine how much memory resource is needed to be allocated for performing a task. The task will fail due to a lack of available memory resources. For example, during the execution of the task, if the task occupies memory resources more than the anticipated amount of memory resources, the task will fail. In the current technology, tasks are allocated with a fixed amount of memory resources. This amount of memory resources is static.

SUMMARY

The system described in the present disclosure is particularly integrated into a practical application of improving memory resource allocation and utilization for executing tasks. This, in turn, provides an additional practical application of improving memory resource allocation and utilization efficiency. As such, technology disclosed in the present disclosure improves memory resource allocation technologies. Further, the technology disclosed in the present disclosure improves underlying operations of computing systems that are tasked with executing the tasks. These practical applications are described below.

Improving Memory Resource Allocations in Database Blocks for Executing Tasks

This disclosure contemplates systems and methods configured to improve (e.g., optimize) memory resource allocation and utilization for executing tasks in database blocks of a database server. The database server may include multiple database blocks. Each database block may correspond to a database that stores a data table used to store data associated with a task and the results of the task. The database server may be referred to as a parent database, and the database blocks may be referred to as child databases. In current technology, in initializing the database blocks of the database server, the database blocks are allocated with a fixed amount of memory resources. This amount of resources is static and not changed during the use of database blocks. In some cases, it may be required to allocate additional memory resources to a database block.

One potential approach may be to allocate the additional memory resource to the database block from the database server (i.e., the parent database). In the current technology, the database blocks may or may not utilize memory resources allocated to them. The current technology is not configured to monitor the memory resource allocations and utilization in the database blocks to determine whether the memory resources are utilized. In contrast, the disclosed system is configured to monitor memory resource utilization in database blocks, identify unutilized memory resources, and reallocate the unutilized memory resources to other database blocks based on the need for memory resources.

In an example scenario, assume that the disclosed system receives a request to allocate a particular amount of memory resources to a particular database block of the database server for performing a task. The disclosed system monitors the database blocks of the database server to determine whether any portion of the memory resources already allocated to databases is unutilized (e.g., is idle). If the disclosed system determines that a portion of memory resources that is already allocated to a database block is unutilized, the disclosed system may reallocate the unutilized memory resources to the particular database block. Thus, the disclosed system may dynamically move (e.g., reallocate) unutilized memory resources between database blocks depending on the need for memory resources. For example, the technology disclosed in the present disclosure improves the current memory resource allocation technology by identifying memory resources that are unutilized and reallocating the unutilized memory resources to database blocks based on the need for memory resources.

In certain embodiment, the disclosed system may monitor the database blocks to identify memory resources that store duplicated data and/or skewed data. The disclosed system may provide a suggestion to delete the duplicated data and skewed data. In response to receiving approval to delete the duplicated data and skewed data, the disclosed system may delete such data, and use the freed memory resources for memory resource allocations and reallocations. In this manner, the disclosed system may improve memory resource allocation and utilization in database blocks of the database server.

In one embodiment, a system for improving memory resource allocation within a database server comprises a database server and a processor. The database server comprises a plurality of database blocks. The database server is associated with total memory resources. Each of the plurality of database blocks is configured to be used to perform a different task. The plurality of database blocks comprises a first database block and a second database block. The processor is communicatively coupled with the database server. The processor receives a first request to allocate a first amount of memory resources from among the total memory resources to the first database block to perform a first task. The processor allocates the first amount of memory resources to the first database block. The processor performs the first task using the first amount of memory resources. The processor receives a second request to allocate a second amount of memory resources to the second database block to perform a second task. The processor monitors the first database block to determine whether any portion of the first amount of memory resources is not utilized. The processor determines that a subset of the first amount of memory resources is not utilized. The processor reallocates the subset of the first amount of memory resources to the second database block.

Improving Memory Resource Allocation in Database Blocks of a Database Server Using Blockchain

This disclosure further contemplates systems and methods configured to use blockchain for improving (e.g., optimizing) memory resource allocation and utilization in database blocks of a database server. In an example scenario, assume that a server receives a request to allocate a particular amount of memory resources to a particular database block to perform a task. The server communicates a blockchain transaction to a block in a blockchain network, where the blockchain transaction comprises the request. The disclosed system provides suggestions to either approve or disapprove the blockchain transaction based on historical blockchain transactions and historical memory resource allocations for performing the task using the particular amount of memory resources. If the blockchain transaction is approved, the disclosed system (e.g., via the blockchain network) generates a new block in the blockchain network indicating the allocation of the particular amount of memory resources to the particular database block.

The disclosed system may generate a new block in the blockchain network for each approved blockchain transaction. The disclosed system monitors memory resource allocations and utilizations in database blocks of the database server. The disclosed system may provide suggestions for reallocating unutilized memory resources (previously allocated to any of the database blocks) to other database blocks where memory resources are needed to perform a task. The disclosed system may distribute the status of memory resource allocations, reallocations, and utilizations among blocks of the blockchain network. For example, the disclosed system may distribute the status of memory resources that are idle (e.g., unutilized), memory resources that store duplicated data, and memory resources that store skewed data among the blocks of the blockchain network. The disclosed system may use this information in providing recommendations for memory resource allocations and reallocations among database blocks. In this manner, the disclosed system may improve memory resource allocations and utilizations in database blocks of the database server. For example, the disclosed system may reduce (or minimize) unutilized memory resources by reallocating them to a database block where memory resources are needed to perform a task. In another example, the disclosed system may reduce (or minimize) memory resources that store duplicated data by recommending to remove the duplicated data and reallocate the memory resources to a database block where memory resources are needed to perform a task. In another example, the disclosed system may reduce (or minimize) memory resources that store skewed data by recommending to remove the skewed data and reallocate the memory resources to a database block where memory resources are needed to perform a task.

In one embodiment, a system for improving memory resource allocation in database blocks of a database server using blockchain comprises a database server, a blockchain network, and a processor. The database server comprises a plurality of database blocks. The database server is associated with total memory resources. Each of the plurality of database blocks is configured to be used to perform a different task. The plurality of database blocks comprises a first database block and a second database block. The blockchain network comprises a first block associated with the database server. The processor is communicatively coupled with the database server and the blockchain network. The processor receives a first request to allocate a first amount of memory resources from among the total memory resources to the first database block to perform a first task. The processor communicates a first blockchain transaction to the first block, where the first blockchain transaction comprises the first request. The processor approves the first blockchain transaction based at least in part upon historical memory resource allocations to perform the first task using the first amount of memory resources. The processor receives a first message from the first block that indicates a second block is generates in the blockchain network. The generation of the second block is in response to the first blockchain transaction being approved. The second block stores allocation of the first amount of memory resources to the first database block. The second block is associated with the first database block. The processor performs the first task using the first amount of memory resources. The processor receives a second request to allocate a second amount of memory resources to the second database block to perform a second task. The processor monitors the first database block to determine whether any portion of the first amount of memory resources is not utilized. The processor determines that a subset of the first amount of memory resources is not utilized. The processor communicates a second blockchain transaction to the first block, where the second blockchain transaction comprises the second request. The processor approves the second blockchain transaction based at least in part upon historical memory resource allocations to perform the second task using the second amount of memory resources. The processor receives a second message from the first block that indicates a third block is generated in the blockchain network. The generation of the third block is in response to the second blockchain transaction being approved. The third block stores reallocation of the subset of the first amount of memory resources to the second database block. The third block is associated with the second database block.

Accordingly, the disclosed system provides several practical applications and technical advantages, which include, at least: 1) technology that improves memory resource allocation and utilization for executing tasks in database blocks of a database server; 2) technology that improves memory resource utilization by identifying unutilized memory resources, memory resources that store duplicated data, and memory resources that store skewed data, and reallocate the unutilized memory resources, and provide a suggestion to delete the duplicated data and skewed data; 3) technology that provides recommendations for memory resource allocation and reallocation among database blocks of a database server based on historical memory resource allocations and reallocations; and 4) technology that distributes memory resource allocations, reallocations, and utilizations among the database blocks, and uses this information to update recommendations for current and future memory resource allocation and reallocation among the database blocks.

As such, the disclosed system may be integrated into a practical application of improving (e.g., optimizing) memory resource allocation and utilization for executing tasks. For example, by implementing the disclosed system, there may be no (or minimum) memory resources that are unutilized, store duplicated data, and/or store skewed data. Thus, the disclosed system may improve the current memory resource allocation technology.

The disclosed system may further be integrated into an additional practical application of improving the underlying operations of systems, including computing systems and databases that serve to perform the tasks. For example, by improving (e.g., optimizing) the memory resource allocation and utilization, fewer memory resources are wasted, remain idle, occupy useless or redundant data. In another example, by improving (e.g., optimizing) the memory resource allocation and utilization, less processing capacity of a computer system that is employed to perform the task is occupied. This, in turn, provides an additional practical application of improving the processing capacity utilization.

Certain embodiments of this disclosure may include some, all, or none of these advantages. These advantages and other features will be more clearly understood from the following detailed description taken in conjunction with the accompanying drawings and claims.

DETAILED DESCRIPTION

As described above, previous technologies fail to provide efficient and reliable solutions to improve memory resource allocation and utilization for task execution. This disclosure provides various systems and methods to improve (e.g., optimize) memory resource allocation and utilization for task execution. Embodiments of the present disclosure and its advantages may be understood by referring to FIGS. 1 through 5 . FIGS. 1 through 5 are used to describe systems and methods for improving (e.g., optimizing) memory source allocation and utilization for executing tasks, and systems and methods for memory source allocation using blockchain.

Example System for Improving Memory Source Allocation for Executing Tasks

FIG. 1 illustrates one embodiment of a system 100 that is configured to improve (e.g., optimize) memory allocation and utilization for executing tasks 106. In one embodiment, system 100 comprises a network 110, a computing device 120, a database server 130, a blockchain network 140, and a server 160. Network 110 enables the communication between components of the system 100. Computing device 120 may be any device used by a user 102. Database server 130 may comprise a plurality of database blocks 132. Database server 130 may be associated with total memory resources 134. Any portion of the total memory resources 134 may be configured to be allocated to any of the database blocks 132. Blockchain network 140 may comprise one or more blocks 142. Blockchain network 140 may generally be configured to keep records of memory resource allocations to the database blocks 132. Server 160 comprises a processor 162 in signal communication with a memory 168. Memory 168 stores software instructions 170 that when executed by the processor 162, cause the server 160 to perform one or more functions described here. For example, when the software instructions 170 are executed, the server 160 executes a processing engine 164 to allocate memory resources 134 to a database block 132 according to suggestions of available and unutilized memory resources 174 recommended by a machine learning module 176. In other embodiments, system 100 may not have all of the components listed and/or may have other elements instead of, or in addition to, those listed above.

In general, system 100 (at the server 160) may receive a first request 104 a to allocate a first amount of memory resources 134 a to a first database block 132 a to perform a first task 106 a. The processing engine 164 determines available (e.g., unutilized) memory resources 134 from among the total memory resources 134. The processing engine 164 may allocate the first amount of memory resources 134 a to the first database block 132 a. The processing engine 164 may continuously or periodically (e.g., every minute, every two minutes, or any suitable duration) monitor memory resource utilization in database blocks 132 a to 132 b. For example, the processing engine 164 may monitor the first database block 132 a to determine whether any portion of the first amount of memory resource 134 a (allocated to the first database block 132 a) is not utilized. The system 100 (at the server 160) may receive a second request 104 b to allocate a second amount of memory resources 134 b to a second database block 132 b to perform a second task 106 b. While monitoring the database blocks 132, assume that the processing engine 164 determines that a subset of the first amount of memory resources 134 a is not utilized (or is no longer utilized). The processing engine 164 may move (e.g., reallocate) the subset of the first amount of memory resources 134 a from the first database block 132 a to the second database block 132 b. In this manner, the system 100 may dynamically allocate and reallocate (e.g., move) memory resources 134 between database blocks 132 to improve (e.g. optimize) the memory resource allocation and utilization for executing tasks 106.

The memory 148 is operable to store block identifier (ID) 150, hash 152 of previous block 142, data 154, and/or any other data and instructions. The block ID 150 may be used to uniquely identify the corresponding network node 142. For example, the block ID 150 may include an alphanumerical serial value. The hash 152 of the previous block 142 may include a hash value 152 of the previous block 142 generated before the corresponding block 142. The order and place of the block 142 in the blockchain 140 may be determined by the hash 152 of the previous block 142.

The memory resource allocation 156 may further include utilization of memory resources 134 allocated to its respective database block 132.

Each block 142 may include information derived from a preceding block 142. For example, every block 142 in the blockchain includes a hash 152 of the previous block 142. By including the hash 152 of the previous block 142, the blockchain network 140 includes a chain of blocks 142 a to 142n from a genesis block 142 a (or a block not shown to the left of the block 142 a in the example of FIG. 1 ) to the latest block 142n (or a block not shown to the right of the block 142n in the example of FIG. 1 ). Each block 142 is guaranteed to come after the previous block 142 chronologically because the previous block's hash value 152 would otherwise not be known.

In an example operation, when a user 102 sends a request 104 to allocate memory resources 134 to a database block 132 to the server 160, the server 160 may transmit the request 104 to the blockchain network 140. Upon approval by the server 160 (e.g., via the machine learning module 176 and/or a user associated with the block 142 a), the blockchain network 140 may generate a new block 142 for the request 104 and store memory resource allocation 156 that indicates the requested memory resources 134 are allocated to the corresponding database block 132. The blockchain 140 adds the newly generated block 142 to the existing blocks 142. The newly generated block 142 may be generated by one or more processors (e.g., processors 144) operably coupled with the components of the blockchain network 140 and/or the system 100. In another example, the newly generated block 142 may be generated by a processor associated with a server configured to create and store the block 142 in the blockchain network 140, and oversee operations within the blockchain network 140. In another example, the newly generated block 142 may be generated by the processor 162 associated with the server 160. The newly generated block 142 may store memory resource allocation 156, corresponding block ID 150, hash 152 of the previous block 142, data 154, and/or any other data. The one or more processors 144 associated with the blockchain network 140 may receive a confirmation that indicates the new block 142 is generated and memory resources 134 are allocated to the corresponding database block 132 as indicated in the request 104. This operation is described in greater detail further below in conjunction with FIG. 3 .

The memory 168 is operable to store the software instructions 170, requests 104 a-c, tasks 106 a-c, memory resources 134, unutilized memory resources 174, machine learning module 176, training dataset 178, messages 312 a-b, and/or any other data or instructions. The software instructions 170 may comprise any suitable set of instructions, logic, rules, or code operable to execute the processor 162.

Processing Engine

Processing engine 164 may be implemented by the processor 162 executing the software instructions 170, and is generally configured to perform one or more operations described herein.

For example, the processing engine 164 may be configured to allocate memory resources 134 to database blocks 132, identify utilized memory resources 134 in database blocks 132, identify unutilized memory resources 174 in database blocks 132, reallocate utilized memory resources 174 from one or more database blocks 132 to a particular database block 132 (based on a request 104 to allocate memory resources 134 to the particular database block 132), provide recommendation for memory resource allocations for database blocks 132, and/or any other operations. The operations of the processing engine 164 are described in greater detail further below in conjunction with the operational flow 200 of system 100 described in FIG. 2 , the operational flow 300 of system 100 described in FIG. 3 , method 400 described in FIG. 4 , and method 500 described in FIG. 5 .

In certain embodiments, the processing engine 164 may be implemented by supervised machine learning, semi-supervised machine learning, and/or unsupervised machine learning module 176. For example, the machine learning module 176 may comprise a support vector machine, neural network, random forest, k-means clustering, etc. In another example, the machine learning module 176 may be implemented by a plurality of neural network (NN) layers, Convolutional NN (CNN) layers, Long-Short-Term-Memory (LSTM) layers, Bi-directional LSTM layers, Recurrent NN (RNN) layers, and the like.

For example, in the training process of the machine learning module 176, the process of memory resource allocation to database blocks 132 may be performed manually by one or more users, operators, database administrators. For example, when a request 104 is received to allocate a particular amount of memory resources 134 to a particular database block 132 to perform a particular task 106, a database administrator may determine whether the request 104 can be approved based on the application and use of the particular task 106, and whether the particular amount of memory resources 134 is required to perform the task 106. The database administrator may approve, reject, or revise the request 104, e.g., by revising the requested memory resources 134. The machine learning module 176 may learn from the selection and behavior of the database administrator with respect to the request 104.

Similarly, during the training process, multiple requests 104 may be received. The process of memory resource allocation to database blocks 132 may be performed manually for the multiple requests 104. The machine learning module 176 may learn from the selection and behavior of the database administrator with respect to the requests 104. In this process, the machine learning module 176 may extract features of each request 104 by feeding each request 104 to a neural network. The features of a request 104 may be represented by a vector of numerical values. The features of the request 104 may represent the requested amount of memory resources 134, the task 106 (indicated in the request 104), the database block 132 (indicated in the request 104), time of day when the request 104 is received, calendar date when the request 104 is received, and/or any other aspect of the request 104. The machine learning module 176 may associate the features of the request 104 to the outcome (or result) of the memory resource allocation requested in the request 104. In this manner, the machine learning module 176 may learn to associate features of each request 104 to its corresponding memory resource allocation result (and its corresponding memory resource utilization. For example, the machine learning module 176 may learn that 85% 80%, etc. of the allocated memory resources 134 requested for a task 106 in a request 104 are utilized.

The machine learning module 176 may generate a training dataset 178 that comprises multiple historical requests 104 each labeled with corresponding features, result of memory resource allocation requested in the request 104, and its respective memory resource utilization. The training dataset 178 may further include historical memory allocations 180. The historical memory resource allocation 180 may indicate the amount of allocated memory resources 134, the source(s) of the allocated memory resources 134 (e.g., which database block(s) 132, the database server 130), and the utilization of the allocated memory resources 134 (e.g., 80%, 85%, etc. of the allocated memory resources 134 are utilized). The processing engine 164 and the machine learning module 176 may use the training dataset 178 to provide a suggestion for memory resource allocation of future requests 104.

During the testing process of the machine learning module 176, the machine learning module 176 may be given a new request 104 that is not labeled with features or result of memory resource allocation and is asked to provide a suggestion for memory resource allocation and determine whether it can be approved, revised, or denied. For example, the new request 104 may indicate to allocate a particular amount of memory resources 134 to a particular database block 132 to perform a particular task 106. The processing engine 164 (e.g., via the machine learning module 176) may analyze the new request 104.

The processing engine 164 (e.g., via the machine learning module 176) may provide a suggestion for memory resource allocation and whether it can be approved, revised, or denied based on the training dataset 178. In this process, the processing engine 164 may extract features of the new request 104, similar to that described above. The processing engine 164 may compare the features of the new request 104 with features of historical requests 104 from the training dataset 178. The processing engine 164 may determine the result of the memory resource allocation of the new request 104 matches (or corresponds) to a historical memory resource allocation 180 of a historical request 104 has matching (or corresponding) features with the new request 104.

In certain embodiments, the processing engine 164 may be configured to provide details about memory resources 134 allocated to any database block 132 that are unutilized, store duplicated data, and/or store skewed data. For example, the processing engine 164 may continuously or periodically (e.g., every minute, every two minutes, or any suitable duration) monitor memory resource utilization in database blocks 132. If a memory resource 134 allocated to a database 132 is not utilized, the processing engine 164 may determine that the memory resource 134 is unutilized. The processing engine 164 may use this information for memory resource allocation and reallocation for database blocks 132.

In certain embodiments, the processing engine 164 may be configured to provide suggestions for moving (e.g., allocating and reallocating) memory resources 134 between database blocks 132 based on their memory resource utilization, training dataset 178, and newly received requests 104. For example, the processing engine 164 may suggest reallocating memory resources 134 already allocated to any database block 132 that are unutilized, store duplicated data, and/or store skewed data to a particular database block 132 that is indicated in a new request 104 to allocate memory resources thereto.

In certain embodiments, the processing engine 164 may be configured to suggest deleting duplicate data and/or skewed data stored in memory resources 134 of any database block 132. For example, the processing engine 164 may suggest to a user or an operator associated with a database block 132 that includes memory resources 134 that store duplicated data, and/or store skewed data, to delete the duplicate data and/or skewed data. The operator can confirm, revise, override the suggestion of the processing engine 164. The processing engine 164 may learn from the action of the operator and include the result of the suggestion to the training dataset 178 to be used for future suggestions and memory resource allocations indicated in future requests 104.

These operations are described in greater detail in conjunction with the operational flow 200 of system 100 for improving (e.g., optimizing) memory resource allocation described in FIG. 2 , operational flow 300 of system 100 for generating a block 142 for memory resource allocations to a database block 132 described in FIG. 3 , method 400 described in FIG. 4 , and method 500 described in FIG. 5 .

Operational Flow for Improving Memory Resource Allocations for Executing Task

FIG. 2 illustrates an example operational flow 200 of system 100 of FIG. 1 for improving (e.g., optimizing) memory resource allocation. In the example FIG. 2 , assume that the database server 130 includes at least three database blocks 132 a, 132 b, and 132 c. Further, in the example of

FIG. 2 , assume that the total memory resources 134 of the database server 130 is a particular amount, e.g., 1000 Giga bits (Gb). Also, assume that the database blocks 132 of the database server 130 have not been allocated with any memory resource 134 yet.

In an example scenario, assume that the processing engine 164 receives a request 104 a to allocate a first amount of memory resources 134 a to the first database block 132 a to perform a first task 106 a. The processing engine 164 may receive the request 104 a from the computing device 120 when the user 102 initiates the request 104 a. For example, assume that the first amount of memory resources 134 a is 125 Gb.

In one embodiment, the processing engine 164 may send this information (e.g., the request 104 a) as a blockchain transaction 210 a to the blockchain network 140. The blockchain transaction 210 a may include details about the request 104 a, such as it is requested to allocate the first amount of memory resources 134 a to the first database block 132 a to perform the first task 106 a. The blockchain network 140 may generate a new block 142 to store information associated with the blockchain transaction 210 a and the request 104 a. This process is described in FIG. 3 . Referring to FIG. 3 , the block 142 a may receive the blockchain transaction 210 a. The block 142 a may be associated with the database server 130. The block 142 a may also be associated with a data owner 310 a. The data owner 310 a may be a user, an administrator, or an operator who has access to the database server 130, and oversee operations of the database server 130. The block 142 a may store the blockchain transaction 210 a. The blockchain transaction 210 a and/or any other data stored in the block 142 a may be stored in data 154 a in memory 148a described in FIG. 1 . The block 142 a may uniquely be identified by the block ID 150 a, similar to that described in FIG. 1 .

If the data owner 310 a approves the blockchain transaction 210 a, the blockchain network 140 generates a new block 142 b to store information associated with the blockchain transaction 210 a and the request 104 a. The block 142 b may be associated with the database block 132 a. The block 142 b may further be associated with a data owner 310 b. The data owner 310 b may be a user, an administrator, or an operator who has access to the database block 132 a, and oversee operations of the database block 132 a. The block 142 b may store the blockchain transaction 210 a. Block 142 b may also store memory resource allocation to the database block 132 a that is approved by the data owner 310 a. The blockchain transaction 210 a and/or any other data stored in the block 142 b may be stored in data 154 b in memory 148b described in FIG. 1 . The block 142 b may uniquely identified by the block ID 150 b, similar to that described in FIG. 1 . The block 142 a may send a message 312 a to the processing engine 164 indicating that the block 142 b is generated.

In one embodiment, the machine learning module 176 may learn from the behavior of the data owner 310 a approving and disapproving blockchain transactions 210 for memory resource allocations to database blocks 132. For example, historical blockchain transactions 210, their respective approval/disapproval indications, memory resource allocations, tasks 106, and other information associated with the historical blockchain transactions 210 may be added to the training dataset 178. The machine learning module 176 may be fed each historical blockchain transaction 210 and its respective approval/disapproval indications, memory resource allocations, tasks 106, etc. The machine learning module 176 may extract features of the historical blockchain transaction 210 and its respective associated information listed above. The extracted features may be represented by vector of numerical values. The machine learning module 176 may learn to associate each historical blockchain transaction 210 with its respective features. Thus, when a future blockchain transaction 210 is received, the processing engine 164 (via the machine learning module 176) may extract its features and determine the extracted features correspond (or match) with which historical blockchain transaction(s) 210. The processing engine 164 may approve/disapprove (or suggest to approve/disapprove) the blockchain transaction 210 based on the historical blockchain transactions 210. In this manner, over time, the process of approving and disapproving blockchain transactions 210 may be performed by the processing engine 164.

Referring back to FIG. 3 , in response to the approval of memory resource allocation to database block 132 a, the processing engine 164 may allocate the first amount of memory resources 134 a from the total memory resources 134 to the first database block 132 a. Thus, the database block 132 a is allocated with (or receives) the first amount of memory resources 134 a. In the example of FIG. 2 , after allocating the first amount of memory resources 134 a to the first database block 132 a, the database server 130 may be associated with 875 Gb, and the first database block 132 a may be associated with 125 Gb. The processing engine 164 may perform the task 106 a using the first amount of memory resources 134 a in the first database block 132 a.

Allocating Memory Resources to a Second Database Block from Unutilized Memory Resources

Continuing the example scenario above, assume that the processing engine 164 receives a request 104 b that indicates to allocate a second amount of memory resources 134 b to the second database block 132 b to perform a second task 106 b. For example, the processing engine 164 may receive the request 104 b from the computing device 120 when the user 102 initiates the request 104 b. For example, assume that the second amount of memory resources 134 b is 25 Gb.

In certain embodiments, the processing engine 164 may send this information (e.g., the request 104 b) as a blockchain transaction 210 b to the blockchain network 140. The blockchain transaction 210 b may include details about the request 104 b, such as it is requested to allocate the second amount of memory resources 134 b to the second database block 132 b to perform the second task 106 b. The blockchain network 140 may generate a new block 142 to store information associated with the blockchain transaction 210 b and the request 104 b. This process is described in FIG. 3 .

Referring to FIG. 3 , the block 142 a may receive the blockchain transaction 210 b. If the data owner 310 a approves the blockchain transaction 210 b, the blockchain network 140 generates a new block 142 c to store information associated with the blockchain transaction 210 b and the request 104 b. The block 142 c may be associated with the database block 132 c. The block 142 c may further be associated with a data owner 310 c. The data owner 310 c may be a user, an administrator, or an operator who has access to the database block 132 c, and oversee operations of the database block 132 c.

The block 142 c may store the blockchain transaction 210 b. Block 142 c may also store memory resource allocation to the database block 132 b that is approved by the data owner 310 a. The blockchain transaction 210 b and/or any other data stored in the block 142 c may be stored in data 154 in a memory 148 of the block 142 c, similar to that described in FIG. 1 with respect to blocks 142 a and 142 b. The block 142 c may uniquely be identified by the block ID 150 c. The block 142 a may send a message 312 b to the processing engine 164 indicating that the block 142 c is generated.

In response to the approval of memory allocation to database block 132 b, the processing engine 164 may allocate the requested memory resources 134 b to the database block 132 b, as described in FIG. 3 .

Referring back to FIG. 2 , the processing engine 164 may monitor the database blocks 132 to determine whether any memory resource 134 allocated to any of the database blocks 132 is unutilized (i.e., not utilized). For example, the processing engine 164 may determine that a memory resource 134 is unutilized if the memory resource 134 is idle and/or if the memory resource 134 is not used to perform a task 106.

In certain embodiments, the processing engine 164 may determine whether data stored in a memory resource 134 allocated in any of the database blocks 132 is duplicated data. For example, the processing engine 164 may determine that data stored in a memory resource 134 of a particular database block 132 is duplicate data if the data is the same (or the duplicate) of another data stored in the particular database block 132.

In certain embodiments, the processing engine 164 may determine whether data stored in a memory resource 134 allocated in any of the database blocks 132 is skewed data. The processing engine 164 may determine that data stored in a memory resource 134 of a particular database block 132 is skewed data, for example, if in a table join operation between two data tables in the particular database block 132, there is not enough space (e.g., memory resources) to allocate to a new table to store the result of the join operation, the new table may include a join operation of some of the two data tables but not all of them. Thus, the result of the join operation between these two data tables may be skewed. In this example, the skewed data corresponds to data that is generated from a joint operation of at least two data tables when there are not enough memory resources 134 available to be allocated to the joint operation leading a result of the joint operation to be skewed. In the present disclosure, unutilized memory resources 174, memory resources 134 storing duplicated data, and memory resources 134 storing skewed data may be referred to as unutilized memory resources 174.

In certain embodiments, upon monitoring the database blocks 132 to determine unutilized memory resources 174 to any of the database blocks 132, the processing engine 164 may provide suggestions for memory resources allocation to the second database block 132 b from the identified unutilized memory resources 174.

In the example scenario of FIG. 2 , assume the processing engine 164 determines that a subset of the first amount of memory resources 134 a (that previously was allocated to the first database block 132 a) is unutilized. For example, assume that the subset of first amount of memory resources 134 a is 5 Gb. Thus, the processing engine 164 may reallocate the subset of first amount of memory resources 134 a from the first database block 132 a to the second database block 132 b.

In an example where the subset of first amount of memory resources 134 a is less than the second amount of memory resources 134 b (i.e., the requested amount of memory resources 134 b to be allocated to the second database block 132 b), the processing engine 164 may allocate the rest of memory resources 134 to the second database block 132 a from the database server 130 (or from the total available memory resources 134 associated with the database server 130). In this operation, the processing engine 164 may determine a difference between the second amount of memory resources 134 b and the subset of first amount of memory resources 134 a. The processing engine 164 may also determine that no other database blocks 132 is allocated with any portion of the total memory resources 134. The processing engine 164 may allocate the determined difference between the second amount of memory resources 134 b and the subset of first amount of memory resources 134 a from the database server 130 to the second database block 132 b.

In the example scenario of FIG. 2 , the processing engine 164 may determine that the difference between the second amount of memory resources 134 b (e.g., 25 Gb) and the subset of first amount of memory resources 134 a (e.g., 5 Gb) is a particular amount of memory resources 134 (e.g., 20 Gb). Thus, the processing engine 164 may allocate the particular amount of memory resources 134 from the available total memory resources 134 associated with the database server 130 to the second database block 132 b. The processing engine 164 may perform the second task 106 b using the second amount of memory resources 134 b in the second database block 132 b.

At the end of this example of allocating the second amount of memory resources 134 b to the second database block 132 b, the total available memory resources 134 maybe 855 Gb memory resources 134, the first database block 132 a may be allocated with 120 Gb memory resources 134 a, and the second database block 132 b may be allocated with 25 Gb memory resources 134 b.

In an example where the second amount of memory resources 134 b is equal to the subset of amount of memory resources 134 a, the processing engine 164 may not have to allocate (and/or reallocate) any memory resources 134 from the database server 130 and/or other database blocks 132 to the second database block 132 b. Thus, the processing engine 164 may perform the second task 106 b using the second amount of memory resources 134 b in the second database block 132 b.

Allocating Memory Resources to a Third Database Block From Unutilized Memory Resources

Continuing the example scenario above, assume that the processing engine 164 receives a request 104 c that indicates to allocate a third amount of memory resources 134 c to the third database block 132 c to perform a third task 106 c. For example, the processing engine 164 may receive the request 104 c from the computing device 120 when the user 102 initiates the request 104 c. For example, assume that the third amount of memory resources 134 c is 100 Gb.

In certain embodiments, the processing engine 164 may send this information (e.g., the request 104 c) as a blockchain transaction 210 c to the blockchain network 140. The blockchain transaction 210 c may include details about the request 104 c, such as it is requested to allocate the third amount of memory resources 134 c to the third database block 132 c to perform the third task 106 c. The blockchain network 140 may generate a new block 142 to store information associated with the blockchain transaction 210 c and the request 104 c, similar to that described above in conjunction with generating new blocks 142 b and 142 c described in FIG. 3 .

The processing engine 164 may monitor the database blocks 132 to determine whether any memory resource 134 allocated to any of the database blocks 132 is unutilized, store duplicated data, and/or store skewed data (collectively referred to herein as unutilized memory resources 174).

In the example of FIG. 2 , assume that the processing engine 164 determines that a second subset of memory resources 134 allocated to one or more database blocks 132 is unutilized. The processing engine 164 may reallocate the second subset of memory resources 134 to the third database block 132 c. For example, the processing engine 164 may determine that the first task 106 a is completed in the first database block 132 a, and the first amount of memory resources 134 a previously allocated to the first database block 132 a is no longer utilized to perform the task 106 a. Thus, the processing engine 164 may reallocate the required amount of memory resources 134 (e.g., 100 Gb) from the first database block 132 a to the third database block 132 b. The processing engine 164 may perform the third task 106 c using the third amount of memory resources 134 c in the third database block 132 c.

Since it is determined that the first amount of memory resources 134 a previously allocated to the first database block 132 a is no longer utilized, the processing engine 164 may revert the rest of the unutilized memory resources 174 from the database block 132 a to the total memory resources 134 associated with the database server 130 indicating that the unutilized memory resources 174 are available to be allocated to any of the database blocks 132.

In certain embodiments, the processing engine 164 may continuously or periodically (e.g., every minute, every two minutes, or any other suitable interval) monitor the database blocks 132 to identify unutilized memory resources 174 allocated to any database block 132. In response, the processing engine 164 may add (e.g., move or revert) the identified unutilized memory resources 174 to the total memory resources 134 associated with the database server 130 indicating that the unutilized memory resources 174 are available to be allocated to any of the database blocks 132. In certain embodiments, allocating memory resources 134 to database blocks 132 may be based on historical memory allocations 180. The historical memory allocations 180 may include historical requests 104 to allocate memory resources 134 to database blocks 132 to perform tasks 106. The historical memory allocations 180 may further include approval indications of memory allocations for performing tasks 106. For example, the approval indications may be provided by users 102 and/or data owners 310. For example, if the historical memory allocations 180 indicate that allocating the particular amount of memory resources 134 to perform a particular task 106 in a particular database block 132 was approved more than a threshold percentage of the time (e.g., more than 80%, 85%, etc.), in response to receiving a new request 104 to allocate memory resources 134 (within a threshold range (e.g., within ±5%, etc.) of the particular amount of memory resources 134 to the particular database block 132 to perform the particular task 106, the processing engine 164 may approve the request 104.

For example, allocating the first amount of memory resources 134 a to the first database block 132 a may be in response to determining that allocating the first amount of memory resources 134 a to the first database block 132 a can be approved based on the historical memory allocations 180 to perform the first task 106 a. In another example, allocating the second amount of memory resources 134 b to the second database block 132 b may be in response to determining that allocating the second amount of memory resources 134 b to the second database block 132 b can be approved based on the training dataset 178, the historical memory allocations 180, and historical requests 104 to perform the second task 106 b, similar to that described above.

In certain embodiments, allocating memory resources 134 to database blocks 132 may be based on historical blockchain transactions 310. For example, allocating the first amount of memory resources 134 a to the first database block 132 a may be in response to determining that allocating the first amount of memory resources 134 a to the first database block 132 a can be approved based on the historical blockchain transactions 310 to perform the first task 106 a.

In certain embodiments, any information and/or data stored in any block 142 of the blockchain 140 may be distributed and shared between the blocks 142.

In certain embodiments, upon identifying memory resources 134 allocated to any of the database blocks 132 that are unutilized, store duplicate data, and/or store skewed data, the processing engine 164 may be configured to send this information as a blockchain transaction 210 to the blockchain network 140. This information may be shared between the blocks 142. For example, the processing engine 164 may suggest to one or more data owners 310 associated with one or more database blocks 132 that include memory resources 134 that store skewed data, to delete the duplicate data and/or skewed data.

In certain embodiments, the processing engine 164 may provide the suggestion of detecting the duplicate data and/or skewed data as a blockchain transaction 210 to the blockchain network 140. The data owner 310 a associated with the block 142 a may use this information to approve, revise, or override the suggestion of the processing engine 164. The processing engine 164 may learn from the action of the data owner 310 a, and include the result of the suggestion to the training dataset 178 to be used for future suggestions and memory resource allocations indicated in future requests 104.

In certain embodiments, upon receiving a request 104 to allocate a particular amount of memory resources 134 to a particular database block 132 to perform a particular task 106, the processing engine 164 may be configured to determine a combination of memory resources 134 and/or unutilized memory resources 174 to be allocated (or reallocated) to the particular database block 132.

In one example, the processing engine 164 may provide multiple suggestions of memory resource allocations. In another example, the processing engine 164 may determine a more optimal memory resource allocation from among the multiple possible memory resources allocations. The more optimal memory resource allocation may correspond to a memory resource allocation where memory resources 134 from database blocks 132 that are unutilized, store duplicate data, and/or store skewed data are prioritized to be used for memory resource reallocation (over the total available memory sources 134 of the database server 130), and the remaining of the memory resources for the memory resource allocation may be taken from the total memory resources 134 available at the database server 130.

In certain embodiments, the processing engine 164 may be configured to hold or suspend a particular task 106 that is determined to require more than a threshold amount of memory resources 134 (e.g., more than anticipated) due to skewness of data created in the middle of the execution of the task 106.

Modifications, additions, or omissions may be made to method 400. Method 400 may include more, fewer, or other operations. For example, operations may be performed in parallel or in any suitable order. While at times discussed as the system 100, processor 162, processing engine 164, or components of any of thereof performing operations, any suitable system or components of the system may perform one or more operations of the method 400. For example, one or more operations of method 400 may be implemented, at least in part, in the form of software instructions 170 of FIG. 1 , stored on non-transitory, tangible, machine-readable media (e.g., memory 168 of FIG. 1 ) that when run by one or more processors (e.g., processor 162 of FIG. 1 ) may cause the one or more processors to perform operations 402-420.

The processing engine 164 may also determine whether any memory resources 134 allocated to any database block 132 stores duplicated data and/or skewed data, similar to that described in FIGS. 1-3 . If it is determined that a portion of memory resources 134 allocated to any database block 132 is unutilized, method 400 proceeds to 418. Otherwise, method 400 proceeds to 416.

At 416, the processing engine 164 allocates the second amount of memory resources 134 b from the total memory resources 134 associated with the database server 130 to the second database block 132 b. The processing engine 164 may then perform the second task 106 b using the second amount of memory resources 134 b, similar to that described in FIGS. 1-3 .

At 420, the processing engine 164 reallocates the subset of the first amount of memory resources 134 a to the second database block 132 b. The processing engine 164 may determine the difference between the subset of first amount of memory resources 134 a and the second amount of memory resources 134 b, and allocate the determined difference memory resources from the database server 130 to the second database block 132 b, similar to that described in FIGS. 1-3 . The processing engine 164 may perform the second task 106 b using the second amount of memory resources 134 b in the second database block 132 b.

In one embodiment, if the processing engine 164 determines that a subset of the first amount of memory resources 134 a store duplicated data, the processing engine 164 may suggest removing the duplicated data to an operator or a user associated with the first database block 132 a. Upon the removal of the duplicated data, the processing engine 164 may reallocate the subset of first amount of memory resources 134 a to any database block 132 (e.g., database block 132 b) where memory resources 134 are needed to perform a task 106.

In one embodiment, if the processing engine 164 determines that a subset of the first amount of memory resources 134 a store skewed data, the processing engine 164 may suggest removing the skewed data to an operator or a user associated with the first database block 132 a.
